AUGUST G. KOLBE, OF DETROIT, MICHIGAN, ASSIGNOR T0 DETROIT OAK BELTINGCOMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

BELT.

To all whom it may concern Be it known that I, AUGUST G. KoLnn, acitizen of, the United States of America, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain new anduseful Improvements in Belts,

of which the following is a specification,

reference being had therein to the accompanying drawings.

The invention relates to driving belts and more particularly to thattype of belt formed of a plurality of sections of leather or the like,secured together.

The invention resides in the peculiar construction, arrangement andcombination of parts as will more fully hereinafter appear and aspointed out in the claims.

In the drawings, Figure 1 is a perspective view of a portion of the beltembodying the invention; Fig. 2 a bottom plan view thereof; Fig. 3 asection on the line a2m of Fig. 2; and Fig. 4 a section on the line g ofFig. 2.

While my invention is adapted for various types of belts, I willdescribe the same as embodied in a wedge-shaped belt for groovedpulleys.

As shown, the belt is formed of a plurality of overlapping sections Awhich are connected together by suitable securing means such as rivetsB, passing through the several overlapping sections. In the constructionillustrated the sections are so overlapped that the rivets each passthrough four sections, the rivets passing through the upper sectionsadjacent their ends C, and through the lower section adjacent theopposite ends D. In order to obtain a substantially uniform thickness ofthe belt the sections are tapered toward the ends D, and in wedge-shapedbelts the sections are also slightly tapered longitudinally.

The parts so far described may be con sidered as forming one ply, whichconsists of several thicknesses of material. Secured to the bottom faceE of this'ply is a second ply F, which in the belt shown, is formed of aplurality of short, spaced sections G of comparatively thick materialwhich are connected to the ply F by the rivets B. These Specification ofLetters Patent.

sections not only serve to increase the thickness of the belt but alsoavoid the ends D being exposed. The belt therefore, may run in eitherdirection.

For certain uses it is desirable to anchor the members G againstturning. This may be accomplished by providing a securing means, with asuitable anchor, and where rivets are used for securing the pliestogether, the side edges I of the rivet head J are turned down andembedded in the section G.

A- belt embodying the invention forms a very strong structure and may bemade of considerable thickness while at the same time, providing a veryhigh degree of flexibility. a

What I claim as my invention is 1. A belt including .1 ply formed of aseries of overlapping comparatively short sections, each section havingits end portions respectively forming portions of the inner and theouter face of the belt, another ply comprising a plurality of shortspaced sections of comparatively heavy material, respectively arrangedover the inner end portions of the sections forming the first-mentionedply, and securing means passing through each section of thesecond-mentipned ply and through the first-mentioned 2. A belt includinga series of comparatively short overlapping sections laterally tapered,each section having its end portions respectively forming portions ofthe inner and outer faces of the belt, a series of comparatively thicksections respectively arranged over the inner ends of the firstnamedsections and having their lateral faces continuous with thecorresponding lateral faces of the first-named sections, and a commonmeans for securing the overlapping sections to each other and thecomparatively thick sections to the overlapping sections.

In testimony whereof I afiix my signature in presence of two witnesses.
